The NXP Nexperia cellular system solution 5210, incorporating an unlicensed mobile access (UMA) software stack from Kineto Wireless, allows devices to be used at home over fixed-line broadband networks and while on the go via a cellular network. The simultaneous usage of Bluetooth and WLAN enables these calls to be made using a Bluetooth headset.

To overcome the challenges of operating WLAN and Bluetooth in the same frequency band and physical co-location without degrading data throughput or voice/audio quality, NXP has integrated a complex set of coexistence algorithms into the 5210?s baseband, its low-power BGW211 WLAN and Bluetooth solutions. This enables both connectivity functions to operate simultaneously without interference while delivering a compelling end-user experience. Additional algorithms have been added specifically for voice applications, ensuring crystal clear communications when using a Bluetooth headset.

The solution requires no additional setup by the consumer. UMA-enabled devices switch seamlessly between cellular networks and Wi-Fi hotspots, automatically detecting the fastest and most cost-effective network ? reducing phone bills and increasing network coverage. UMA is particularly attractive to business users, with Wi-Fi use in offices, airports and hotels growing exponentially, offering substantial savings in mobile bills.

Handsets based on NXP Nexperia cellular system solution 5210 are already on the market. The UMA/Bluetooth enhanced platform will be available in the first half of 2007. A demo will be available at the NXP booth at 3GSM ? Hall 8, booth #110.
